Karl Barth was the most influential theologian of the twentieth century, and his work continues to inspire both fresh theological thinking and critical debate. The period covered by the volumes in this series–1905 to 1933 –saw Barth emerge from his training under such theological giants as Adolph von Harnack and Wilhelm Herrmann; assert his rejection of liberal Protestant theology in his towering commentary on Romans; and work through an earlier uncertainty to become a critic on theological grounds of the rise of Nazism. These volumes contain essays, lectures, academic papers, correspondences, editorials, and other writings that were not previously translated into English and that provide insight into the development of Barth's theology during this crucial period of his life.
